IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 138,529, dated May 6,1873; application filed February 20, 1873.

. mattress or bed-bottom composed of an upper and a lower frameinclosing and surrounding a resting surface composed wholly of spiralsprings, connected together at one end by a wire fastening which unitesthe upper coil of one spring with the upper coil of the spring next toit, and at the other end by metallic cross-bands, and the row of springsnearest the frames being secured to the same by clasps, or some othersuitable fastening, all as will be hereinafter more fully explained.

In the accompanying drawing, Figure 1 is a plan view of the upper sideor top of my bed bottom or mattress. Fig. 2 is a plan view of the underor bottom side of the same. Fig. 3 is a longitudinal vertical sectiontaken on the plane of the line as a, Fig. 1. Fig. 4 is an enlarged sideView of the fastening for the tops of the springs at the upper side ofthe bed 7 bottom. Fig. 5 is an enlarged detail view, showing moreplainly the method of fastening the springs to the outside frame of thebed-bottom or mattress; and Fig.6 is a detail view, showing the mannerof connecting together the springs at the bottom or under side of thesame.

A designates the upper, and B the lower, metallic frames, which'arepreferably made of hoop-iron. In the present instance the bed bottom ormattress is made in two parts or sections of substantially the samedimensions, to facilitate handling and transportation, the said sectionsbeing hinged together, so that the one can be readily folded over andupon the other-say, by hinges a. a (see Fig. 1,)- connecting the twoparts or sections of the upper frame. In this case strengtheningstrips bb and c 0, running from one side of the frame to the other, are founddesirable.

I will here remark that the frames A B may be continuous to constitutethe entire lateral and longitudinal dimensions of the bed-bottom, inwhich case, of course, no hinges on a would be employed, nor need thecrossstrips 1) b c c be employed.

The frames are provided with round cor ners where they are to be usedwith the styles of bedsteads now in common use. The corners are maderound by the use of semicircular pieces, riveted at their respectiveends to the side and end strips of the frame, respectively, as will bereadily understood by reference to Figs. 1 and 3.

The upper frame A and the lower frame B are connected together, and thespace inclosed by them is filled up with spiral springs 0, all of whichmay be of the pattern termed hourglass springs e but I prefer to usesome conical spiral springs fin connection with the hour-glass springs.At the top or upper side of the mattress'the springs are connectedtogether by a fastening, D, consisting of a simple piece of Wire loopedover the upper coil of two adjacent springs, and the ends bent.

down so as to prevent disengagement, as will be clearly understood byreference to Fig. 4. At the bott-tom or lower side of the mattress thesprings are connected together by two bands, E E, of hoop iron crossingeach other and having their respective ends secured to the outer coilsof adjacent hour-glass springs, as will be clearly understood byreference to Fig. 6. At the crossing of the bands E E the small end of aconical spiral spring is secured by passing its outside coil at this endunder and over the said bands alternately, and hooking its end over thenext or second coil. In fact, it is desirable to hook the ends of eachouter coil over that next to it for strengthening the outer coils. Thesprings which lie between the frames A B are secured to said frames byclasps F riveted to the frames,

closed spiral or hour-glass springs (J, the latter fastened together atone end by the loop-- fastening D and at the other end by the crossbands E E, and both ends being secured to the said surrounding-frames,substantially as herein specified.
